TECHNICAL FIELD

The present disclosure relates to a method and apparatus for registering a wireless device in a wireless communication system.

BACKGROUND

In recent years, due to the increase in use of wireless communication, there is an increasing demand for connecting new wireless communication devices to the communication network. In addition, there is a need for temporary connection between wireless devices based on wireless communication technology, and in this case, pairing should be performed between the wireless devices.

In a related-art wireless communication system, the pairing may be performed by an application installation process and a device registration/authentication process according to the related art. The application installation process represents a process in which a user searches for and downloads an application for pairing, which is deployed by an operator, or downloads and installs a pairing application, which is provided from a separate provider.

The device registration/authentication process may include a process of recognizing a wireless device for pairing, with minimized power, registering the wireless device by receiving a personal identification number (PIN) code, blocking the registration of other wireless devices during pairing, and performing encrypted communication through the exchange of authentication keys. The device registration/authentication process will be described in detail below.

A wireless device used for registering devices (hereinafter referred to as a ‘device registration-purpose wireless device’) may perform registration for adjacent wireless devices in order to minimize transmit power. Therefore, the device registration-purpose wireless device should move to the place adjacent to the wireless device that the device registration-purpose wireless device will register, or a wireless device subject to the registration procedure should move to the place adjacent to the device registration-purpose wireless device. In this way, for pairing between two wireless devices, the two wireless devices should be placed adjacent to each other by the user. Therefore, the existing device registration method may be limited to the user-dependent method because the user's active involvement is required.

If the two wireless devices exist in the adjacent places, a communication environment for communication between the two wireless devices may be provided, and a PIN code may be used for encrypted communication. The device registration-purpose wireless device may provide a PIN code that is randomly generated, or provided from an associated system, to a relevant wireless device, and determine the wireless device to which a PIN code corresponding to the provided PIN code is applied, as a wireless device that the device registration-purpose wireless device will register, thereby performing the registration procedure.

When performing the registration procedure, the device registration-purpose wireless device may block any devices from involvement in the registration during the registration procedure by ignoring all the other adjacent devices for a period of a preset time.

For security, two wireless devices, which are not open before pairing, may exchange keys needed for authentication using separate wired communication (e.g., universal asynchronous receiver/transmitter (UART) communication or the like) and closed wireless communication (e.g., infrared data association (IrDA) communication or the like), and then, perform a registration procedure through an authentication process. The two wireless devices may perform the registration procedure through encrypted security communication, using Peer-to-Peer (P2P) communication of near field communication (NFC).

In this pairing scheme, even though pairing is normally performed, another wireless device adjacent to the device registration-purpose wireless device is likely to be registered, instead of the wireless device that the user desires to register. In addition, the pairing scheme may undergo complicated pairing settings, because application installation and device registration should be separately performed, instead of being performed as one process, and identifiers (IDs) and passwords for multiple items are required.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

An aspect of the present disclosure provides a method and apparatus for registering a wireless device in a wireless communication system. The present disclosure provides the following four possible embodiments depending on the type of the wireless communication used by a wireless device and a terminal.

The terminal proposed in the first to fourth embodiments of the present disclosure may include cellular phones, tablet personal computers (PCs) and the like, all of which are capable of wireless communication. However, the wireless device and the terminal may not be limited to the above devices, and may include any other devices.

Each of the four embodiments of the present disclosure will now be detailed in detail.

FIG. 1 illustrates a wireless communication system according to a first embodiment of the present disclosure.

Referring to FIG. 1 , the wireless communication system according to the first embodiment of the present disclosure may be configured in the form of a home network, which includes a wireless device 100, a terminal 110, an access point (AP) 120, a home server 130, and may include other similar and/or suitable devices.

The wireless device 100 may perform Wi-Fi communication, and include a recognition code including device information and the like. The recognition code may be a 2-dimensional (2D) recognition code. The recognition code 105 may correspond to, for example, a quick response (QR) code 105 and the like, and for convenience of description, the recognition code will be referred to herein as a QR code 105.

In the first embodiment of the present disclosure, the QR code 105 may include connectivity type information indicating the wireless communication type such as Wi-Fi and the like, information about the operation mode that the terminal 110 should enter in a registration process, a Wi-Fi medium access control (MAC) address, a service set identifier (SSID) and a password, which are used for tethering a connection, uniform resource identifier (URI) information for download of an application, and the like. The above information may be encrypted and then stored in the QR code 105, and the URI information may be recorded in accordance with the QR standard.

The terminal 110, a device capable of performing Wi-Fi communication, may obtain information included in the QR code 105 by scanning the QR code 105. The terminal 110 may enter the tethering mode based on the information obtained from the QR code 105, making it possible to perform a registration procedure for the wireless device 100.

The AP 120 may be connected to the home server 130 and perform communication with the external network. For example, if the terminal 110 transmits URI information, the AP 120 may deliver an application corresponding to the URI to the terminal 110.

The home server 130 may be connected to the external network and the AP 120, and manage information about a variety of devices in the home network.

Reference will now be made to FIG. 2 , to describe a process of registering a wireless device in the wireless communication system illustrated in FIG. 1 .

FIG. 2 is a signaling diagram illustrating a process of registering a wireless device in a wireless communication system according to the first embodiment of the present disclosure.

Referring to FIG. 2 , in operation 200, the terminal 110 may obtain information about connectivity type, operation mode, Wi-Fi MAC address, SSID, password, application URI and the like by scanning the QR code 105 included in the wireless device 100. In operation 202, the terminal 110 may download and install an application using the URI information. The application may correspond to an application used for searching for and registering of the wireless device 100, and the terminal 110 may download the application through the AP 120.

The terminal 110 may execute the application and determine the connectivity type and operation mode included in the QR code 105. In operation 204, the terminal 110 may enter the tethering mode based on the SSID and password, if it is determined that the connectivity type corresponds to Wi-Fi and the operation mode is a station (STA)/AP mode (in which a terminal (or a station) operates as an AP, and a wireless device operates as a terminal for the AP, thereby performing a registration mode). The terminal 110 may start operating as an AP.

In operation 206, the wireless device 100 may recognize the terminal 110 that operates as an AP. For example, the wireless device 100 may recognize the terminal 110 as an AP that has the same SSID and password as the SSID and password included in the QR code, through a periodic AP scan process. The wireless device 100 may recognize the terminal 110 by determining that the terminal 110 is adjacent to the wireless device 100, by means of a proximity sensor or the like.

Upon recognizing the terminal 110, the wireless device 100 may transmit a connection request message to the terminal 110 in operation 208. Herein, although the wireless device 100 may transmit the connection request message immediately after recognizing the terminal 110, the wireless device 100 may transmit the connection request message by receiving a separate input from a user after informing the user of its recognition of the terminal 110 using a display, a voice sign or the like.

Upon receiving the connection request message, the terminal 110 may perform a Wi-Fi connection operation to the wireless device 100 in operation 210. The terminal 110 may be connected not only to the wireless device 100 but also to a plurality of wireless devices, since the terminal 110 operates as an AP. Therefore, the terminal 110 should detect the wireless device 100 that the terminal 110 desires to register, among the plurality of wireless devices connected to the terminal 110. To this end, in operation 212, the terminal 110 may detect the wireless device 100 among the plurality of wireless devices connected to the terminal 110, based on the Wi-Fi MAC address.

For example, the terminal 110 may broadcast a request signal for discovery of a wireless device to the plurality of wireless devices using a simple service discovery protocol (SSDP)/multicast domain name system (mDNS) or another discovery protocol, and then receive a response signal thereto. The terminal 110 may detect, as the wireless device 100, the wireless device that has transmitted a response signal including the same Wi-Fi MAC address as the Wi-Fi MAC address that the terminal 110 knows.

Upon detecting the wireless device 100, the terminal 110 may encrypt AP access information including the information needed for an access to the AP 120, and transmit the encrypted AP access information to the wireless device 100 in operation 214. In operation 216, the terminal 110 may terminate the tethering mode. Although the terminal 110 may terminate the tethering mode immediately after transmitting the AP access information, the terminal 110 may terminate the tethering mode after receiving a signal indicating the reception of the access information of the AP 120, from the wireless device 100.

After terminating the tethering mode, the terminal 110 may access again the AP 120 in operation 218. In operation 220, the wireless device 100 may access the AP 120 based on the AP access information received from the terminal 110. The wireless device 100 may transmit its own information to the AP 120. Then, the AP 120 may transmit the information about the wireless device 100 to the home server 130 so that the information about the wireless device 100 may be registered in the home network.

The terminal 110 may detect wireless devices connected to the home network, using the SSDP/mDNS or another discovery protocol. The terminal 110 may allow the user to select at least one of the detected wireless devices by displaying information about the detected wireless devices on the screen. If the user selects the wireless device 100, the terminal 110 may transmit a pairing request to the wireless device 100 and receive a response signal thereto. In operation 222, upon detecting the connection to the wireless device 100, the terminal 110 may perform registration for the wireless device 100.

Next, reference will be made to FIGS. 3 and 4 , to describe operations of the terminal 110 and the wireless device 100 according to the first embodiment of the present disclosure, respectively.

FIG. 3 is a flowchart illustrating an operation of a terminal according to the first embodiment of the present disclosure.

Referring to FIG. 3 , in operation 300, the terminal 110 may obtain device information (e.g., connectivity type, operation mode, Wi-Fi MAC address, SSID, password, application URI and the like) by scanning the QR code 105 of the wireless device 100. In operation 302, the terminal 110 may download and install an application using the URI.

In operation 304, the terminal 110 may execute the application, and if the connectivity type corresponds to Wi-Fi and the operation mode is the STA/AP mode, the terminal 110 may enter the tethering mode using the SSID and password. In operation 306, upon receiving a connection request from the wireless device 100 while the terminal 110 operates as an AP in the tethering mode, the terminal 110 may perform a connection operation to the wireless device 100. In operation 308, the terminal 110 may determine whether the connected wireless device is a relevant wireless device (e.g., the wireless device 100) based on the Wi-Fi MAC address, because the terminal 110 may be connected not only to the wireless device 100 but also to another wireless device.

If it is determined in operation 310 that the connected wireless device 100 is the relevant wireless device, the terminal 110 may encrypt AP access information and transmit the encrypted AP access information to the wireless device 100 in operation 312. In operation 314, the terminal 110 may terminate the tethering mode and access the AP 120.

The terminal 110 may detect wireless devices connected to the home network using the SSDP/mDNS or another discovery protocol. The terminal 110 may allow the user to select at least one of the detected wireless devices by displaying information about the detected wireless devices on the screen.

If the user selects the wireless device 100, the terminal 110 may transmit a pairing request to the wireless device 100, and receive a response signal thereto. In operation 316, the terminal 110 may determine its connection to the wireless device 100 and register the wireless device 100.

FIG. 4 is a flowchart illustrating an operation of a wireless device according to the first embodiment of the present disclosure.

Referring to FIG. 4 , in operation 400, the wireless device 100 may detect the terminal 110 operating as an AP, based on the SSID and password included in the QR code 105. The wireless device 100 may detect the terminal 110 as an AP that has the same SSID and password as the SSID and password included in the QR code 105, through a periodic AP scan process. After determining that a specific terminal is adjacent to the wireless device 100 by means of a proximity sensor or the like, the wireless device 100 may detect or discover the terminal 110 by determining whether the specific terminal is the terminal 110 based on the SSID and password included in the QR code 105.

In operation 402, the wireless device 100 may transmit a connection request message to the detected terminal 110 and perform a connection operation. Upon receiving a request signal for discovery from the terminal 110, the wireless device 100 may transmit the Wi-Fi MAC address included in the QR code 105 using a response signal, allowing the terminal 110 to detect the wireless device 100.

After performing the above process, upon receiving AP access information from the terminal 110 in operation 404, the wireless device 100 may access the AP 120 based on the received AP access information in operation 406. The wireless device 100 may transmit its own information to the AP 120 so that the wireless device 100 may be registered in the home network. Upon receiving a pairing request by the terminal 110, the wireless device 100 may pair with the terminal 110 in operation 408.

Next, a description will be made of the second embodiment of the present disclosure, in which a terminal performing Wi-Fi communication registers a wireless device performing Wi-Fi communication by performing P2P communication with the wireless device.

FIG. 5 illustrates a wireless communication system according to a second embodiment of the present disclosure.

Referring to FIG. 5 , the wireless communication system according to the second embodiment of the present disclosure may be configured in the form of a home network, which includes a wireless device 500, a terminal 510, an AP 520, a home server 530, and may include other similar and/or suitable devices.

The wireless device 500 may perform Wi-Fi communication, and include a recognition code including device information and the like. The recognition code may be a 2D recognition code. The recognition code may correspond to, for example, a QR code 505 and the like, and for convenience of description, the recognition code will be referred to herein as a QR code 505.

In the second embodiment of the present disclosure, the QR code 505 may include connectivity type information indicating the wireless communication type such as Wi-Fi and the like, information about the operation mode that the terminal 510 should enter in a registration process, a Wi-Fi MAC address, a P2P personal identification number (PIN) code used to perform P2P communication, URI information for download of an application, and the like. The above information may be encrypted and then stored in the QR code 505, and the URI information may be recorded in accordance with the QR standard.

The terminal 510, a device capable of performing Wi-Fi communication, may obtain information included in the QR code 505 by scanning the QR code 505. The terminal 510 may perform a registration procedure for the wireless device 500 by performing P2P communication with the wireless device 500 based on the information obtained from the QR code 505.

The AP 520 may be connected to the home server 530 and perform communication with the external network. For example, if the terminal 510 transmits URI information, the AP 520 may deliver an application corresponding to the URI to the terminal 510.

The home server 530 may be connected to the external network and the AP 520, and manage information about a variety of devices in the home network.

Reference will now be made to FIG. 6 , to describe a process of registering a wireless device in the wireless communication system illustrated in FIG. 5 .

FIG. 6 is a signaling diagram illustrating a process of registering a wireless device in a wireless communication system according to the second embodiment of the present disclosure.

Referring to FIG. 6 , in operation 600, the terminal 510 may obtain information about connectivity type, operation mode, Wi-Fi MAC address, P2P PIN code, application URI and the like by scanning the QR code 505 included in the wireless device 500. In operation 602, the terminal 510 may download and install an application using the URI information. The application may correspond to an application used for searching for and registering of the wireless device 500, and the terminal 510 may download the application through the AP 520.

The terminal 510 may execute the application and determine the connectivity type and operation mode included in the QR code 505. In operation 604, the terminal 510 may enter a Wi-Fi P2P mode by turning on a Wi-Fi interface, if it is determined that the connectivity type corresponds to Wi-Fi and the operation mode is the P2P mode (in which a terminal performs a registration procedure by performing P2P communication with a wireless device). The terminal 510 may detect at least one wireless device for P2P communication, and perform a P2P connection operation based on the P2P PIN code in operation 606.

Specifically, the terminal 510 may broadcast a request signal for discovery of a wireless device, and then receive a response signal thereto. The terminal 510 may detect the wireless device that has transmitted the response signal, as a wireless device for P2P communication in operation 608. The terminal 510 may detect, as a wireless device for P2P communication, the wireless device that has transmitted the same P2P PIN code as the obtained P2P PIN code, among the wireless devices that have transmitted the response signal, and perform a connection operation to the wireless device for P2P communication. The P2P PIN code may be transmitted together with the response signal, or transmitted in a separate signal from the at least one wireless device. Here, the terminal 510 may determine whether the connected wireless device is the wireless device 500, based on the Wi-Fi MAC address. In other words, the terminal 510 may determine, as the wireless device 500, the wireless device that has the same Wi-Fi MAC address as the Wi-Fi MAC address that the terminal 510 knows.

If the connected wireless device is determined to be the wireless device 500, the terminal 510 may encrypt AP access information for the AP 520 and transmit the encrypted AP access information to the wireless device 500 in operation 610. In operation 612, the terminal 510 may terminate the Wi-Fi P2P mode and turn off the Wi-Fi interface. Although not illustrated in FIG. 6 , the terminal 510 may terminate the P2P mode after receiving a signal indicating the reception of the AP access information from the wireless device 500.

After the termination of the P2P mode, the terminal 510 may access again the AP 520 in operation 614. In operation 616, the wireless device 500 may access the AP 520 based on the AP access information received from the terminal 510. The wireless device 500 may transmit its own information to the AP 520. Then, the AP 520 may transmit the information about the wireless device 500 to the home server 530 so that the information about the wireless device 500 may be registered in the home network.

The terminal 510 may detect wireless devices connected to the home network, using the SSDP/mDNS or another discovery protocol. The terminal 510 may allow the user to select at least one of the detected wireless devices by displaying information about the detected wireless devices on the screen. If the user selects the wireless device 500, the terminal 510 may transmit a pairing request to the wireless device 500 and receive a response signal thereto. In operation 618, upon detecting the connection to the wireless device 500, the terminal 510 may perform registration for the wireless device 500.

Next, reference will be made to FIGS. 7 and 8 , to describe operations of the terminal 510 and the wireless device 500 according to the second embodiment of the present disclosure, respectively.

Referring to FIG. 7 , in operation 700, the terminal 510 may obtain device information (e.g., connectivity type, operation mode, Wi-Fi MAC address, P2P PIN code, application URI and the like) by scanning the QR code 505 of the wireless device 500. In operation 702, the terminal 510 may download and install an application using the URI.

In operation 704, the terminal 510 may execute the application, and enter the Wi-Fi P2P mode and detect a wireless device for P2P communication, if the connectivity type corresponds to Wi-Fi and the operation mode is the P2P mode. In operation 706, the terminal 510 may perform a P2P connection operation to the detected wireless device based on the P2P PIN code.

In operation 708, the terminal 510 may determine whether the detected wireless device is the relevant wireless device 500, based on the Wi-Fi MAC address. If it is determined in operation 710 that the detected wireless device is the relevant wireless device 500, the terminal 510 may encrypt AP access information and transmit the encrypted AP access information to the wireless device 500 in operation 712. In operation 714, the terminal 510 may terminate the Wi-Fi P2P mode and access the AP 520.

The terminal 510 may detect wireless devices connected to the home network, using the SSDP/mDNS or another discovery protocol. The terminal 510 may allow the user to select at least one of the detected wireless devices by displaying information about the detected wireless devices on the screen.

The method according to embodiments of the present disclosure may be implemented by a computer or a portable terminal, which includes a controller and a memory. It can be noted that the memory is an example of the machine-readable storage medium suitable to store a program or programs including instructions for implementing embodiments of the present disclosure.

Therefore, the present disclosure may include a program including codes for implementing the method and apparatus as defined by the appended claims and their equivalents, and also include a non-transitory machine (e.g., computer or the like)-readable storage medium storing the program. In addition, the program may be electronically carried on any media such as communication signals that are transmitted through wired/wireless connections.

As is apparent from the foregoing description, according to embodiments of the present disclosure, the information (e.g., Wi-Fi MAC address, and SSID and password for tethering connection in the case of Wi-Fi; Zigbee MAC address and install key in the case of Zigbee; and SRP key and URI for download of an application in the case of Z-wave) needed for the registration procedure may be stored in the QR code mounted on a wireless device, thereby to omit the input procedure which was conventionally performed by the user, making it possible to perform the fast and easy device registration procedure.

In the case of a Zigbee wireless device, if a security scheme such as an elliptic curve cryptography (ECC) scheme or the like is used, a security key input procedure for an install key or the like is required.
